I stayed in Ohm's apartment for two lots of 3 nights in June 2017.
Organising the booking was super easy and the directions for the apartment made things very simple for taking cabs.
Tha apartment was great, it's a standard comfy studio, with all the basic amenities. On the plus side it's got a big comfy bed, good aircon and a good flow shower (which is a big plus for me), worth being aware of is the bathroom floor gets pretty wet as the shower is level with the floor (but it was never a major issue) and it's probably not a self catering apartment though why would you want to I'm not sure when there are so many great places to eat in the neighbourhood including a local Thai food hall in the basement of the building. There is only a small counter top refrigerator so only room for a couple of big bottles of water and some fruit maybe.
The building is in a great location about 1/2 way between Sala Daeng and Chong Nonsi BTS stations and walking distance to silom MRT. Great local markets in the lane ways around the condominium including food. And an awesome Western style cafe for breakfast (Tazzina) just around the corner so definitely worth a visit. Great food and coffee.
I'll definitely stay again and have no hesitation in recommending Ohm's place as a comfy central place to explore and experience Bangkok
